Red face Brake conversion: (single to dual)

I have a 1966 mustang with power drum brakes. For safety reasons I want to install a dual master cylinder on it. Can some one give me a part number of a master cylinder that will bolt up to my present power brake booster. (If not a part number the make, model and year of the master cylinder you used. I would apricate any help someone can give me. Thank you and have a nice day. Beachamp1. I have an automatic transmission.

Just go to CJ Pony or Dallas Mustang, or one of the other parts houses. They'll give you exactly what you need.

There is a chance that you will need to adjust the rod length of the booster; I would certainly want to check it before bolting on the new m/c. A tool like the one at the link below can help. I have used a similar one; there are cheaper ones on eBay.

Here is a you-tube vid that shows you how to adjust the Push rod in the Master cylinder when you change the master cylinder.

The best option IMHO....is to go with a 1974 Maverick....ask for V8, Power Drum...it will be an exact match and operate perfectly.

thanks for the input, I will try a 1976 Maverick power brake master cylinder on my booster and see how it works out. Beechkid: thanks for that information. Bob

I'd go with eliminating the power boost drum and use dual bowl manual set up for better feedback response from the pedal. It's an upgrade a lot of folks do and is pretty simple.

I bolted up a '95 Cobra master cylinder. It's got the same bolt pattern and bore size as the '65 with disc brakes, but it's aluminum with a plastic reservoir. And it uses metric tube nuts instead of standard.

T5 transmission with hydraulic clutch. Griggs Racing GR350 suspension. 8.8 rear end. Griggs front & Wilwood rear brakes. Many more mods to come!
